Technical field

The utility model is related to hardware tool field more particularly to a kind of adjustable wrenches.

Background technology

Adjustable wrench is a kind of common installation and extracting tool, using lever principle, for fastening and rising loose different rule The nuts and bolt of lattice.

In the prior art, adjustable wrench is usually formed with fixed spanner and movable jaw, the fixed spanner in one end of handle Bayonet is formed with movable jaw, and fixed spanner and movable jaw are in parastate for the side of clamping.When in use, it is sharp The size for the bayonet that fixed spanner and movable jaw are formed is adjusted with rotation worm gear, has its clamping and waits to press from both sides there are two parallel surface Object is held, such as：Nut, threadingly direction of rotation apply external force at handle, so as to twist nut.

However, adjustable wrench applicable surface of the prior art is narrow, the object to be held with parallel surface is only applicable to.

Utility model content

The utility model provides a kind of adjustable wrench, can be suitable for the circles such as irregular nut, round nut and/or steel pipe Material adds the use scope of adjustable wrench, solves the problems, such as that adjustable wrench applicable surface is narrow in the prior art.

The utility model provides a kind of adjustable wrench, wherein, including handle, rotate worm gear, fixed spanner and movable jaw, institute The one end for stating handle is equipped with the fixed spanner and the movable jaw, and the fixed spanner and the movable jaw form card Mouthful, for the rotation worm gear for adjusting the bayonet size, the fixed spanner and the movable jaw are used for the side of clamping It is provided with teeth.

By using the size for rotating the bayonet that the fixed spanner of worm gear adjusting and movable jaw are formed so that adjustable wrench can press from both sides Different size of object is held, by setting teeth in fixed spanner and movable jaw for the side of clamping so that object to be held Frictional force increase between part and bayonet, so as to which adjustable wrench can clamp object of different shapes, including irregular nut, circular spiral shell Female and/or round steel pipe etc., asking for the object to be held with parallel surface can only be clamped by solving adjustable wrench of the prior art Topic expands the use scope of adjustable wrench.

Optionally, the side of the fixed spanner and the movable jaw for clamping is arc.

Arc is arranged to by the way that the side of spanner and movable jaw for clamping will be fixed, in adjustable wrench gripping objects, The frictional force between object and bayonet can further be increased, also, the bayonet that fixed spanner and movable jaw are formed is arc Structure, can cause adjustable wrench can gripping objects scope more extensively, such as：Not specification nut, round nut and/or circle Steel pipe etc., and the clamping action of above-mentioned object is more fastened.

Optionally, the other end of the handle is equipped at least one first through hole, and the first through hole inner edge has friction Surface.

Optionally, the friction surface is toothed surfaces.

By setting at least one first through hole in the other end of handle, and the inner edge of first through hole has friction surface, So that the first through hole can mating sleeve use, for fasten or rise loose ground position it is narrow and small or recess very deep bolt or nut； Further, the friction surface of first through hole is set to toothed surfaces, first through hole and the frictional force of sleeve can be increased so that It is more preferable with the use of effect with sleeve.

Optionally, the first through hole be at least two, at least two first through hole it is of different sizes.

Optionally, at least two first through hole is uniformly arranged in the other end of the handle.

By setting at least two first through hole, and at least two first through hole is of different sizes so that it is described extremely The sleeve that few two first through hole can match different size uses, so as to further expand the use scope of adjustable wrench；It is logical It crosses and is uniformly arranged at least two first through hole in the other end of the handle, each first through hole can be caused to use Get up more convenient.

Optionally, the adjustable wrench further includes at least one second through hole, and second through hole is polygon.

Optionally, the polygon is hexagon.

By being equipped at least one second through hole in the adjustable wrench other end, second through hole is polygon so that described Adjustable wrench can also have the function of fixed fork spanner, available for fastening or play pine and the matched bolt of the second through hole or nut, behaviour Facilitate；Further, since common bolt or nut are hexagon, second through hole is shaped to six sides Shape so that the second through hole can match the bolt used or the scope of nut is more extensive, the utilization rate higher of the second through hole, so as to Adjustable wrench need not be pulled when fastening or rising the hexagon bolt or nut of loose regular size by rotating worm gear adjusting by fixation The bayonet size that head and movable jaw are formed using matched second through hole can directly fasten or rise loose hexagon bolt or spiral shell It is female.

Optionally, the fixed spanner is 30 °~100 ° for the radian of the side of clamping, and the movable jaw is used to press from both sides The radian for the side held is 30 °~100 °.

By by fix spanner for clamping the radian of side be set to 30 °~100 °, the movable jaw is used to press from both sides The radian for the side held is set to 30 °~100 °, and the bayonet that fixed spanner and movable jaw can be caused to form more conducively clamps not The object of similar shape, and clamp more secured.

Optionally, the fixed spanner is integrally formed with the handle.

It is integrally formed by the way that spanner will be fixed with handle so that adjustable wrench is more convenient during fabrication, reduces the zero of adjustable wrench Number of packages amount, and make the intensity higher of adjustable wrench, it is more robust, increase the service life of adjustable wrench.
